Abstract

In the processing of semiconductor wafers, a problem occurs when attempting to remove wafer carrying receptacles or containers from a batch processing tank. Typically, the receptacles have a lip or rim to facilitate removal and carrying of the receptacle if the process tank is dry and/or for transportation of the receptacle to another process station. However, when the process station is filled with a liquid, then means must be provided for removing the receptacle from the tank without danger to the operator.

Detachable Handle Grip

In the processing of semiconductor wafers, a problem occurs when attempting to remove wafer carrying receptacles or containers from a batch processing tank. Typically, the receptacles have a lip or rim to facilitate removal and carrying of the receptacle if the process tank is dry and/or for transportation of the receptacle to another process station. However, when the process station is filled with a liquid, then means must be provided for removing the receptacle from the tank without danger to the operator.

Referring to the drawing, a simple detachable gripper and handling apparatus 10 is illustrated. As shown, a flexible hand grip 11 is connected to spaced apart rods 12 which terminate in inturned clips or rim engaging grips 13. Slidably mounted on the rods 12 is a bar or release latch 14 which is biased by springs 15 to space the release latch from the flexible handle 11. Inboard release rods 16 are connected to the release bar 14 and terminate in latches 17, which serve to grip the interior of the container or receptacle while the clip or grip 13 captures the rim thereof.

When it is desired to release the container or receptacle, the release latch or bar 14 and hand grip 11 are gripped simultaneously and squeezed causing the latches 17 to be lifted away from the interior of the container. Increased squeezing of the hand grip 11, upon the stops 18 impinging upon the handle, causes the hand grip 11 to flex inwardly effecting outward spre...
